SPECIFICATION forming part of Letters Patent No. 716,165, dated December16, 1902.

Application filed March 1B, 1902. Serial No. 98,833. (No model.)

To all whom t may concern.; i

`Be it knownthat I, JOSEPH ALsFAssER, a citizen of the United States,and a resident of Chicago, county ofCook, and State of Illinois, haveinvented certain new and useful Im-L provements in Bottle-Stoppers, ofwhich the following is; a specification, and which are illustrated inthe .accompanying drawings, forming a part thereof.

This invention relates to a stopper which is especially intended for usewith bottles and other receptacles for containing beverages bottledunder pressure, such as carbonated liquids, although it may be employedin lieu `of the ordinary attached stopper.

In bottling liquids under pressure the common type of stopper, connectedby a bail to the neck of the bottle, is impracticable, inasmuch as thebail would be in the way of the plunger of the bottling-machine andinterfere with the proper 'sealing of the bottle. For this reason it hasgenerally been the practice to employ an independent or non-attached capor stopper adapted tobe fixed in place by crimping or compressing itaround the lip of the bottle and which after once being removed is notintended to be used again, no means being provided for securing it inplace. This type of stopper is objectionable, owing to the fact that itcannot be employed for reclosing the bottle after it has once beenunsealed, so that the contents remain open to the atmosphere and soonbecome flat and stale, and a new cap or stopper must be used each timethe bottle is returned for refilling. These difculties are overcome inthe present invention, which consists of a cap or stopper of peculiarconstruction adapted to be engaged and secured by the yoke or bail of anordinary stopper-fastener attached to the bottle and which is soarranged that while it maybe removed from the fastener during thebottling operation the said fastening device may be secured `to the`stopper to hold the same in place and to permit of its being used inthe manner of the ordinary attached stopper.

The invention consists of the combination and arrangement of partshereinafter fully stopper. Fig. 2 is a section on the line .fr a; ofFig. 1. Fig. 3 is a view of the cap for securing the yoke or bail of thefastener to the stopper. Fig. 4 is a section on the line Y Y of Fig. 2.Fig. 5 is a side elevation of the stopper secured to a bottle by anordinary bail and closing-lever. Fig. 6 is a vertical diametricalsection of a modification of the bottle-stopper. Fig. 7 is a top View ofthe same with the bail-retaining cap removed, and Fig. 8 is a verticaldiametrical section of another modification of the stopper.

Referring to the construction illustrated in Figs. 1 to 4, inclusive, 10indicates a cylindrical casing, preferably provided with a flaring upperend 11 and having Vertical slots 12 at diametrically opposite points.Seated in the upper end of the cylindrical casing is a cup-shaped diskor member 13, also provided with vertical slots 14, adapted to registerwith the slots 12 of the cylindrical casing. In order to secure the cup13 in the casing, the latter is provided with tangs or flanges 15, whichare designed to be bent inwardly through the registering slots 12 and 14and about the Walls of the slots in the cup. The cylindrical casing 10below the cup 13 is provided with an internal annular rib 1.6 forsecuring in place a sealingdisk,of cork or rubber,adapted to restagainst the lip of' the bottle when the stopper is secured in place.

For retaining the stopper on the bottle I employ any of theusualstopper-fasteners designed to be permanently attached to thebottle, such as that shown in Fig. 5, where 17 designates the bail oryoke and 18 the lever attached to the bottle and connected to the bailfor drawing the latter down to hold the stopper over the mouth of thebottle.

In use the stopper is held to the lip of the bottleJoy thebottling-machine in the usual manner, and the bail 17 is then placed inthe registering slots of the cylindrical casing and cup containedtherein and drawn down by the closing-lever 18 to secure the same. A

cap 19 is then placed over the fiaring top of the cylindrical casing andsecured thereto by crimping or in any other suitable manner. As thusarranged the stopper is, in effect, permanently attached to the bottle,and after the latter has once been opened the stopper may be used toclose the same until the con- IOO tents have become exhausted. When thebottle is returned for refilling, the cap 19 is removed, so that thebail-fastening device may be detached in order not to interfere with theoperation of the bottling-machine when the bottle is recharged, and thesame stopper may be used over and over again.

The invention is susceptible of various modifications, andl do not limitmyself to the exact construction heretofore described. For instance, thestopper may be made as shown in Figs. 6 and '7, where 10iL indicates thecylindrical casing, 12a the vertical slots therein to receive thestopper-fastenin g bail or yoke, and 19a the cap for retaining the bailin the slots. In this construction the sealing-disk 16 is retained in aninverted-cup-shaped member 13, placed in the bottom of the cylindricalcasing and provided with an annular rib for securing the cup 13L inposition, and seated in the upper part of the cylindrical casing is adisk or ring 20, held in position by iianges 2l, extending from thecasing through the slots thereof and into grooves 22 in the top of thering or disk 20.

In the modification shown in Fig. 8 the cylindrical casing 101 and Jtheinverted cup 13a, in Which the sealing-disk 16a is seated, may bestamped from a single piece of metal. In other respects thisconstruction is similar to that shown in Figs. 6 and 7.

I claim as my invention- 1. In a bottle-stopper, in combination, acylindrical casing, a sealing-disk therein, a disk located Within thecasing and over the sealing-disk, slots in the cylindrical casing andwhich are designed to receive the bail or yoke of a stopper-fastener,the casing being provided With iianges extending through the slots forsecuring the latter disk in place, and a removable cap for thecylindrical'casing and for holding the bail or yoke against removal fromthe slots.

2. In a bottle-stopper, in combination, a cylindrical casing, asealing-disk therein, vertical slots in the opposite Walls of thecylindrical casing, a cup seated in the casing above the sealing-diskand having vertical slots coinciding With the slots in the casing,flanges extending from the casing through the slots therein and bentabout the Walls of the slots in the cup, and a removable cap for thecasing and for closing the upper ends of the slots.

3. In a bottle-stopper, in combination, a bottle, a cylindrical casing,a sealing-disk therein, vertical slots in the opposite Walls of thecylindrical casing, a cup seated in the casing above the sealing-diskand having vertical slots coinciding with the slots in the cylindricalcasing, means for securing the cup Within the casing, a bail resting inthe slots, a closing-lever attached to the bottle and for moving thebail to secure the stopper in the bottle, and a removable cap for thecylindrical casing and for holding the bail against removal from theslots thereof.
